These days, the New York Knicks aren't the only ones embarrassing themselves at Madison Square Garden.

Just feet outside the World's Most Famous Arena, where the Knicks have floundered to a 5-28 record, Justin Bieber put on a performance that he'd probably like to have back.

A skateboarding aficionado, the 20-year-old pop star was spotted practicing his craft in Midtown Manhattan. Dressed in black pants, a black sweatshirt and a black Chicago Bulls hat (more on that later), Bieber recorded several falls before pulling off his desired trick. Here's a video of Bieber's boarding, with the biggest tumble coming at the :34 mark:

In Bieber's defense, he's not afraid to embarrass himself in public. This isn't the first time he's laughed off a skateboarding miscue, and he's even posted video of himself wiping out.

Bieber uploaded this photo of him riding through the streets Monday:


Look at the lady to the left she's like wtf is going on

As for Bieber's hat, well, that's a little bit harder to defend than his poor skateboarding. Especially for someone with questionable NBA allegiances (he's worn Clippers and Lakers gear the past few years). But there is some evidence suggesting that the Biebs is now a Bulls fan.

For one, he attended the season opener between Chicago and New York at Madison Square Garden. He was also spotted several weeks ago wearing a different Bulls hat.

It seems Bieber is still on board the Los Angeles Clippers' bandwagon, but it's hard to blame him for rooting for the Bulls. Chicago is 21-9 and one of the favorites to win the Eastern Conference. Remembering what Bieber has done to the other teams with which he's associated recently, the Bulls might want to keep their distance.
